No one was injured, but the police urged residents in the area to stay away from windows during the night.
A gate to a rental house is more or less blown away, says Johan Josarp, duty officer at the police.
The police issued a so-called VMA, important message to the public, with a call to residents in the area to stay indoors and keep away from windows. At 02.20, it was announced that the danger was over.
The alarm about the explosion came at 23.40 on Thursday evening. In addition to the gate, cars parked on the street also suffered shrapnel damage. No one was injured, according to the police.
Technicians are on site and securing evidence. We are hearing witnesses and working further, says Josarp.
On Friday morning, the police announced that two people had been arrested, suspected of gross general endangerment.
